CROSS-TIE. I

Specification of Letters Patent.

Patented May 4, 1915.

Application filed February 24, 1915. Serial No. 10,181.

To all whom it may concern Be it known that I, JOSEPH F. CARPENTER, a citizen of the United States of America, and resident of Wheeling, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Cross-Ties, of which the following is a specification.

This invention relates broadly to'railway crossties, and specifically to a reinforced concrete crosstie.

The primary object of the invention is to provide a concrete crosstie having cushioning blocks of wood disposed therein to constitute elastic seats for the rails.

A further object is to provide improved means for mounting the wooden blocks in place whereby the cushioning effect is heightened. And a still further object of the invention is to provide reinforcing means of improved form.

With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinationsv of elements which will hereinafter be fully described, reference being hereinhad to the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation of a crosstie embodying my invention, showing rails mounted thereon; Fig. 2 is a top plan view of the same; Fig. 3 is a longitudinal section on the line 3-3, Fig. 2; and Figs. 4 and 5 are perspective views of the reinforcing members.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views1 indicates a crosstie formed of concrete, cement, or like indestructible material or composition, which has formed in its upper face adjacent to each of its opposite ends a recess 2 of plain rectangular form adapted for receiving therein a wood block 3 having plain per pendicular sides. Said blocks constitute seats for the track rails 4 which are secured in place thereon by means of vertically disposed bolts 5, said bolts having their heads 6 countersunk or seated in sockets 7 provided therefor in the under face of the block. The upper threaded ends of said bolts carry nuts 8 which seat upon suitably formed plates 9 disposed at opposite. sides of the rail in clamping relation to the base of the latter. v

Embedded in the concrete and projecting upward through the bottom of the recess 2 is one or more dowel-like pins 10 having heads '11 anchored in the concrete. pins seat in sockets 12 provided therefor in the under face of the block 3 and serve to maintain said block against endwise movement while offering no obstruction to up ward springing movement of said blocks. This is an important feature of this invention, as, in order that a maximum elastic cushioning efi'ect may be afforded, it is essential that the block shall be free to work vertically up and down within the recess.

WVhile any suitable reinforcing means may be employed in the crosstie, I prefer to employ two unconnected members 13 and 14:, the former being a plain bar or plate having upturned ends 13 and disposed so as to occupy a position closely adjacent to the under side and ends of the tie. The member 14 consists of a bar or plate shaped to form a straight body portion 14 adapted to lie adjacent to the upper face of the tie between the recesses 2, downwardly bowed recessunderlying portions 14 and horizontal return portions 14 the latter lying adjacent to the top face of the tie between the recesses and the ends of the tie.

What is claimed is 1. A concrete crosstie having a recess formed therein adjacent to each of its ends, said recess having vertical side walls, a wood block fitted in said recess and having vertical faces, means projected through said block for securing a rail thereon, and dowel pins embedded in the concrete and projecting vertically into said recess, the upper ends of said dowel pins being received in sockets provided in said block.

A concrete crosstie having a recess formed therein adjacent to each of its ends, said recess having vertical side walls, a wood block fitted in said recess and having ver tical faces, rail attaching bolts projecting upward through said block, vertically disposed dowel pins anchored in the concrete and having their upper ends extending into said recess and received in sockets provided therefor in the under side of said block.

3. A concrete crosstie having a recess formed therein adjacent to each of its ends, saidrecess having vertical side walls, a wood block fitted in said recess, said block having vertical faces and having sockets in its under side, rail-attaching bolts directed through said block and having their heads counter- Said , having sockets in its under side, rail-attaching bolts directed through said block and having their heads countersunk in the under side thereof, and vertically disposed dowel block being so disposed that vertical movement of said block is not interfered with.

In testimony whereof, I afiix my signature in presence of two subscribing witnesses.
